HIPPO- PATHOLOGY. 
remote from the heart. The lungs will still continue very si 
to attack because they especially suffer from over-exertion ; 
the brain and eyes will at this period be failing ; the bowels also 
will now experience occasional disorder from the astringent nature 
of the animal’s food, from the constipations they become subject to 
for want of proper exercise, and from the disturbances caused in 
their functions by violent bodily exertion. 
This distribution of diseases between the growing and adult 
periods of a horse’s life will, of course, vary with the regimen he 
is subjected to, i. e., his stable management, the nature and quan- 
tity of the work he is made to perform, and other circumstances. 
The view I have taken of the subject is a general one : that the 
facts stated are worthy of some credit — whether the explanations 
coupled with them be plausible or not — will appear from the sub- 
joined table : —

From this tabular statement, to the extent that it goes, we learn 
that pulmonary disorders are more prevalent among horses prior to 
and during the fifth year of their age, the period of their growth 
and domestication, than at any subsequent time ; after that time 
that they become obnoxious to diseases of the bowels, and occa- 
sionally of the brain ; and that ophthalmia is a disorder especially 
prevalent at the adult or most vigorous stage of life. 
To enable us to pursue this interesting inquiry still further — 
to shew at what particular seasons, and months even, these dis- 
orders, respectively, prevail (though this is a matter necessarily 
greatly influenced by weather and situation), — I have, from “ Re- 
gisters of sick and lame horses” regularly kept for many years, 
drawn up the following table :
